UNITED STATES WILLIAM RUBE, OF OFALLON, ILLINOIS.

STOVE.

T 0 all whom it may concern:

Be it known that I, WILLIAM RUBE, a citizen of the United States, and resident of OFallon, Illinois, have invented certain new and useful Improvements in Stoves, of which the following is a specification.

- This invention relates to improvements in stoves and consists in the novel arrangement, construction and combination of parts as will be fully hereinafter described and claimed.

The object of my invention is to construct a stove having a fire box provided with flues to permit a down draft to pass under the grate and out through a flue to the chimney.

A further object of my invention is to provide a fresh air pipe to distribute the air centrally upon the top of the fire within the fire box to assist in burning the smoke, gases and particles of combustion, and flues provided on the fire box to provided the proper draft, permitting it to pass downwardly to the fire box so as not to overheat the magazine in the upper portion of the stove.

A further object in connection with the fire box, fresh air flue and the flues provided on the fire box, is to add an auxiliary base of grill work to permit the heat to pass outwardly on all four sides and yet prevent the floor from becoming overheated by the excessive heat passing through the ash pit.

In the drawings: Figure 1 is a central vertical sectional view of my complete invention. Fig. 2 is a horizontal sectional view with parts broken away taken on the line 22 of Fig. 1 and viewing the same in the direction indicated by the arrow. Fig. 3 is an enlarged detail sectional view of a portion of the fire box showing one of the fines made use of in carrying out my invention. Fig. 4is a detail central sectional view of the fresh air distributing pipe made use of in connection with my invention.

In the construction of my invention I provide a base 5 having a door 6 in which is formed a slide damper of the usual construction, the said base acting as an ash pit and in the same is placed an ash pan 7. The said base 5 in mounted upon an auxiliary base the sides thereof being skele ton in form or provided with openings for the passage and circulation of heat and air. The said base 8 is mounted upon the usual stove legs 9. In the bottom of the aux iliary base I place a shield 10 which extends across the greater portion of the base, and the object of the same is to deflect the Specification of Letters Patent.

heat generating from the ash pit from contacting with the floor.

The upper portion of the base 5 is pro vided with an opening 11 in which is placed a grate 12 and around the opening and formed integral with the top of the base is a flange 13 which supports and retains in position the fire box 14.

The fire box 14 is composed of two tapering cylinderical sections 15 and 16. The section 15 forming the inner wall is of such material as to withstand the excessive heat of the fire, and the outer section which is located around the inner section is provided with grooves 17 which act as flues or circulating passages between the inner and outer sections. At the upper end of the inner section and at the point where the flues are located are provided openings 18 in which is mounted a sliding damper 19 preferably constructed of the ordinary slide damper type, and through this opening is permitted to pass and circulate the heat to be conveyed downwardly and under the grate.

Upon the top of the fire box and communicating with the upper edge of both sec tions forming the fire box is located a flanged ring 20. In the ring just above the flues formed in the fire box are provided elongated slots 21 through which project damper rods 22 by which the slide dampers 19 are operated. The flanged ring 20 is also provided with an elongated opening 23 through which is passed the smoke flue 24, the lower end of said flue communicating with the ash pit and the upper end supported to the top casting.

Upon the flanged ring 20 is mounted the stove casing or shell 26 and upon the top of said casing or shell is supported the top casting 25. In the front of the stove casing or shell is provided a stove door 27 andthrough said shell and near the smoke flue is provided an opening 28 through which is passed the horizontal member 29 of the fresh air pipe 30. The vertical member of the fresh air pipe is passed downwardly through an opening formed in the flanged ring 20 through the ash pit, and its lowest end projecting slightly below the shield 10, the inner end of the horizontal member being located centrally above the fire box and so arranged as to distribute fresh air over the fire to assist in burning all particles of combustion.

said magazine can be easily and readily re'' movd from the stove when soft coal is to be used. On the top of the casting 25 is placed the ordinary cover 36 of any ornamental design.

In the top casting 25 and at right angles to the smoke flue 24 is provided an opening 37- which permits circulation between the chimney and the casing or shell.

Inthe top casting 25 is pivotally mounted a damper 38 so arranged as to close and open communication between the chimney and the casing or shell, or the chimney and the smoke flue 24'.

The operation of: my invention is as follows: In the first instance, when building a fire in myimproved'stove, Iopen the damper 38' by placing it in:the'position as shown in Fig. 1. The'darnper 32 in the freshair pipe is closed; the dampers 19 in thefire box are closed, and the damper located in the door of the ash pit is opened; The materialwithin the fire box is then ignited and the draft is direct from the fire boxup- Wardlythrough the opening 37 to the chimney. When the fire hasbeenp'roperly ignit'ed'the damper in'the door ofthe' ashp'it is-closed, the damper 38 inthe top casting placed in reversed position; closing the opening 37, and the damper 32 in the fresh air pipe is open so as to permit the fresh air to circulate upwardly through the pipe and over the fire box. The dampers in the flues of the fire boxare also open, permitting the draft to circulate downwardly, not

through the grate, but through the flues: formed between the sections of thefire'boxand permitting'the heat to pass through the ash pit and upwardly through the smoke flue 24 out through the chimney. By: this construction there is supplied suflicien't' fresh airfrom the bottom, delivered above the fire box to mix with the particles of cornbustion and burn all particles thereof thus causing a more steady and excessive heat and prevent the grate bars from melting orburning out.

By meansof the flues formed'in th'e fire box the grates are preserved and a better result is accomplished.

Havin fully described my invention, what I claim is:

1. A stove of the class described comprising a fire box of two sections; a base; an auxiliary base; flues formed in thefi'r'e box between the two sections; dampers located in the upper ends of the flues and a fresh air supply pipe for conveying fresh air from'the bottom' of the stove" to the top of" the fire box, substantially as' specified.

2. A stove of the class described comprising a base; an auxiliary base; a fire box; flues formed in the firebox extendingf'rom the top of thefire box down to the base;

dampers located in the upper ends of said flues; a stove casing mountedupon the'fire box; a smoke flue communicating with the base and with the top of the stove,,and a fresh air pipe for supplying fresh air upon the top of the fire box, collecting: the air from below the auxiliary base, and a damper" lo cated in the fresh air pipe for regulating the 1 2iirculation of the air, substantially asspeci- 3. A stove of the class described-comprising a stove casing; a fire box located beneath the stove casing, said fire box composed of two sections; a pair of fiues formed in the fire box between the two sections extending from thetop of said fire box down to the base; slide dampers'located in the upper end of the 'inner'seotionof the fire box to control the circulation between the fire box and the flues; a base supporting the fire box, saidbase acting as the ash pit; an auxiliary base supporting the first mentioned'base besides, said auxiliary base being in skeleton form; a fresh air pipe extending horizontallyin'to the stove casing and located above the fire-- box, said fresh air pipe also bent downwardly and extending through the bases for collecting air from beneath the auxiliary base and delivering it upon the fire within the firebox; a shield partially extending across the bottom of-the auxiliaryb'as'e to deflect the heat; and a damper located in the air'pipe'for-regulatingthe circulation of air; substantially as specified.

In testimony whereof, I" have signed myname to this specification, in presence'oftwo subscribing witnesses.
